Application filed July 6, 1905- Serial No, 268,455.

To all whom, it may concern:

Be it known that I, HENRI LHUILLIER, chemical engineer, a citizen of theRepublic of France, residing at Paris, in the Republic of France, haveinvented certain new and useful Improvements in Apparatus for DyeingThreads on Cops and Pirns, (for which application has been made inFrance January 24, 1905, No. 350,981; Austria-Hungary, April 7, 1905Germany, February 9, 1905, and Belgium, January 25, 1905,) of which thefollowing is a specification.

This invention has for its object an improved apparatus for dyeingthreads of yarn on cops or pirns.

In this arrangement the cops to be dyed are mounted on hollow perforatedspindles permanently fixed on the pipes conveying the dye-bath. Thesepipes are connected in sets of four by means of a union which connectswith a central conduit runningfrom one end of the vat to the other. Thiscentral conduit is movable and is detachably connected, by means oflower tubes, to another conduit fixed on the bottom of the vat. Thespindle-carrying pipes thus form a sort of rack in one with the centralfeed-conduit and may be removed as a single piece. In this manner thehandling is extremel simple, resulting in a saving of labor and e cientworking of the vat. Further, by this invention the cops when placed onthe spindles cannot be displaced or lifted by the pressure of theliquid, because they are held by means of strips, which prevent theirlifting.

The method of carrying out the invention is hereinafter describedwithreference to the accompanying drawings, in which Figure 1 is a planview, and Fig. 2 a transsection, of .the vat; Fig. 3, an elevation, onan enlarged scale, of the end of a pair of tubes; and Fig. 4, a planview of this on The apparatus comprises a rectangular vat 1, preferablyof wood. The cops 2 to be dyed are fitted on perforated hollow spindles3, fixed by soldering or otherwise on rows of pipes 4. These pipes arearranged in pairs on the right and left sides of the vat and areconnected in sets by means of a union piece 5, provided beneath with aneck 6, which fits into a corresponding socket 7 on a central conduit 8.The various branches are thus arranged parallel to each other, so as tooc- The conduit 8 is provided with several pipes 9, which fit into necks10, connecting with a pipe 11, arranged form a pair are connected bycross-pieces l3, which serve as supports to vertical rods 14.

In connection with these are arranged flat strips 15, connected byplates 16, and in the middle of the latter sockets 17 are fixed.

When the cops are in place, the pairs of strips 15 are placed along eachdouble row of cops, so as to bear on the conical heads of the cops andkeep them on the spindles. The engagement of the sockets 17 with therods 14 keeps the strips 15 in place, and the weight of these lattersufiices to hold the cops. If this be not sufficient, the rods 14 may bearranged to project above the plates 16 and provided with fixingdevices. As the strips 15, as shown, are quite thin, and thereforeflexible, they retain the cops in place without unduly compressing someof them, while leaving others free, as would result with a rigid piece.Also it is to be noted that the strip 15 only moves contact with eachcop at a single point, thereby preventing spots which would result froma more extended contact. In order to enable the conduit 8 to be takenout and replaced, the walls of the vat are provided with grooves 18, inwhich tongues at each end of the conduit 8 engage.

The cover (not shown in the drawings) is provided with the necessarypipes for establishing communication with a circulationpump and avacuum-pump, also a manometer, a tap for the readmission of air, andother connections, as desired. The bottom of the vat is provided withsteam-coils 19 for heating the bath.

The working of the apparatus is as follows: When the spindles have beenfitted with cops or pirns and the whole is placed in the vat and the lidfixed, the vacuum-pump is set in o eration. The dye-bath is then drawninto t e vat by the pipe 11, the conduit 8, the pipes 4, and theperforated spindles 3 through the cops or pirns. By opening the air-tappressure is reestablished in the upper part of the vat, and the dye-bathredescends by gravitation. The operation may be repeated several timesif such be deemed necessary. Washing may be done in the same manner. Theliquid may also be caused to circulate in the vat by means of a pump.When the operation is terminated, the conduit 8 and all the pipes,carrying the spindles with their bobbins, is removed in a single piece,and the vat is provided with a fresh set of pipes carrying spindles,which has been prepared outside the vat. From this it is evident thatthe operations in the vat may succeed one another without interruptionother than that necessary for removing one set of spindlecarrying pipesand replacing it by another, which operation isfacilitated by thecircumstance that all the pipes are mounted on the central conduit, sothat they may be simultaneously removed. The cops may be dried on thespindles by sending a current of warm air under pressure through thecentral conduit 8 and forcing it through the cops.

I declare that what I claim is 1. In an apparatus for dyeing threads onspindles in order to have a circulation of liquid, the combination ofrectilinear pipes, perforated spindles fitted thereon, cops mounted onsaid spindles with blades making contact with the head of the cops forpreventing the cops being lifted on the spindles, substantially asdescribed.

2. In an apparatus for dyeing threads and yarns in cops, the combinationof a conduit, spindle-carrying pipes arranged at an angle to saidconduit and parallel to each other, and strips adapted to prevent thecops of the same row from being lifted, substantially as described.

8. In an apparatus for dyeing threads in cops, the combination ofspindle-carrying pipes connected in pairs, cross-pieces connecting theends of the pipes of each pair, rods mounted on said cross-pieces,strips for preventing the cops from being lifted on the spindles, platesconnecting the ends of the strips, and hollow rods fixed at one end onsaid plates and at theirother ends telescoping onto the first-namedrods.

4. In an apparatus for dyeing threads and yarns in cops, the combinationof a vat, a removable rectilinear conduit therein, rectilinear pipesfixed to and connecting with said conduit in pairs and arrangedtransversely thereto and parallel to each other, hollow perforatedspindles carried by said pipes, cross-pieces connecting the ends of thepipes of each pair, guide-pieces projecting from said cross-pieces, thinflexible strips in contact at a single point with the heads of the rowsof cops for retaining the cops upon the spindles, other cross-piecesconnecting together the ends of the strips, and other guidepiecesprojecting from the last-named crosspieces and telescoping with thefirst-named guide-pieces.

5. In an apparatus for dyeing threads and yarns in cops, the combinationof spindles arranged in rectilinear rows, and a thin flexible blade,contacting at a single point with the head of each cop in a row forretaining the cops upon the spindles.

6. In an apparatus for dyeing threads and yarns in cops, the combinationof hollow perforated upwardly projecting spindles arranged inrectilinear rows, a thin flexible blade resting with its weight upon theheads of the cops in a row and making contact with each cop at a singlepoint, and means for guiding said blades.

In witness whereof I have hereunto signed my name, this 31st day of May,1905, in the presence of two subscribing witnesses.

HENRI LHUILLIER.
